Abstract

Ten patients in whom tissue proliferation akin to angioglioma occurred within the brain are described; seven of the lesions were supratentorial and three infratentorial. Only 31 accepted instances of such neoplasms have been found in the literature. The combined lesions usually become symptomatic in the second and third decades. In all 10 cases, the angiomatous part of the combined tumors showed characteristic vascular malformation such as severe hyalinization, tortuosity, and some were even calcified. The number of abnormal blood vessels were excessive in all examples. The glial portion consisted of either astrocytoma, oligodendroglioma, or mixtures of these gliomas. Dedifferentiation of the neuroglia combined with neoplastic endothelial proliferation indicates the true neoplastic nature rather than reactive gliosis associated with a vascular anomaly. © 1996 Wiley-Liss, Inc.
